Abstract
Abstract. This paper aims to develop a strategy for architectural knowledge modeling in order to actively support the built heritage conservation process by fostering collaboration among stakeholders and interoperability between datasets. The integration of two modeling systems, one ontology-based and one in BIM environment, seems to be the right way to meet this objective: the former is rather exhaustive to represent the semantic contents of conservation activities, especially non-geometrical data, the latter is absolutely suitable to represent the logic of the construction, above all geometrical-constructive aspects typical of any architectural organism. Thus, this study proposes a side-by-side approach to synchronize these different ways of representing reality by managing the complexity of cultural heritage on the one hand and of technology tools, such as information systems, on the other. The proposed methodology was tested on the city walls of San Ginesio (Macerata, Italy) and included different steps considering the in-use technologies (notably geomatics and information technologies) as key enablers to acquire, hierarchically order, model and enrich the knowledge of that heritage site. The result is a knowledge-led strategy moving from survey to HBIM implementation, as a way to enhance representation and management in architectural heritage processes.

This paper aims to develop a strategy for architectural knowledge modeling in order to actively support the heritage conservation process by fostering collaboration among stakeholders and interoperability between datasets
The present study developed an integrated approach to architectural knowledge modelling combining an empirical and visual and descriptive (3D model) representation of a historical site as a way to enhance knowledge acquisition, representation and management in built heritage processes
Summary
The need to make the heritage conservation and enhancement processes coordinated and planned has been established at a theoretical and legislative level for several years now. Art. of the D.M. 154/2017 - Regolamento concernente gli appalti pubblici di lavori riguardanti i beni culturali tutelati explicitly refers to the above-mentioned article and clarifies that public interventions on cultural heritage have to be implemented «according to the timescales, priorities and recommendations deriving from the criterion of planned conservation» Heading in this direction means developing an operative methodology able to collect, hierarchically organize, and interconnect and manage heterogeneous data (different sources, contents, scales of representation, levels of detail and development, etc.) related to historical architectures and sites in the medium-long term, ensuring accessibility and shareability of information among stakeholders during the various phases of the conservation process. To exploit the potential of Information and Communication Technology (ICT) while respecting the discipline of heritage protection and its specificities, the approach to artefacts (survey, modeling and data enrichment) has to be based on knowledge as a guiding principle; in this sense, it is possible to talk about ‘knowledge modeling’ as several authors have recently highlighted (Acierno 2017; Acierno et al, 2017; Fiorani 2017)
